“…Besides the project FLAME2008, the service connector is also used in service roaming (Gartmann, Holtkamp, Weissenberg, & Li, 2005) and the project AMGrid 2 (CAFISE, 2003), which targets virtual enterprises among different manufacturing companies. The experiences from real-world projects show that with the model, language and tools presented in this paper, a service-oriented application has the following advantages:…”

Dynamic changes of services and requirements require service connection relationships adaptable in service compositions. This paper presents an adaptable service connector model and related language and tools. The model presents service connection relationships as an explicit component with which service connections can be reconfigured and changes of services involved in the interaction can be handled; this makes the service connection relationships more adaptive. With the language and tools supporting the model, services can be dynamically chained, which make service-oriented applications adapt to volatile business requirements and dynamic changeable services. The related case study and evaluation are also presented in this paper.

“…This section concentrates on reviewing previous work on communication middleware in continuous service execution environments. Continuous service execution, studied as service roaming in related work [ 17 , 18 ], enables the consumption of services in a mobile environment. Services are only valid in a specific scope, becoming useless where the user moves outside it.…”

Abstract:Mobile prosumer environments require the communication with heterogeneous devices during the execution of mobile services. These environments integrate sensors, actuators and smart devices, whose availability continuously changes. The aim of this paper is to design a reference architecture for implementing a model for continuous service execution and access to capabilities, i.e., the functionalities provided by these devices. The defined architecture follows a set of software engineering patterns and includes some communication paradigms to cope with the heterogeneity of sensors, actuators, controllers and other devices in the environment. In addition, we stress the importance of the flexibility in capability invocation by allowing the communication middleware to select the access technology and change the communication paradigm when dealing with smart devices, and by describing and evaluating two algorithms for resource access management.

An Ontology-Based Approach to Personalized Situation-Aware Mobile Service Supply

Mobile devices such as personal digital assistants (PDAs) and mobile phones are in widespread use already today and converging to mobile smart phones. They enable users to access a wide range of services and information without guidance through their actual demands. Especially during mass events like the Olympic Games 2008 in BeijingVwhich was initially the context of our workVa large service space is expected to support all mobile visitors, being athletes, journalists, or spectators. Current approaches tackling such problems are location based, meaning that a user's location is central to service provision, and even context-aware, meaning that, beyond location, characteristics of a user's environment are taken into account. Such information obviously helps to deliver relevant information at the right time to the mobile users. Going one step further, a situation-aware system abstracts from the context dimensions by translating specific contexts into logical situations. Knowing the situation end users are in allows the system to better identify the information to be delivered to them and to choose the appropriate services with regard to their scope, which is referred to as service roaming. Even though many context frameworks have been introduced in the past few years, what is usually missing is the notion of characteristic features of contexts that are invariant during certain time intervals. This paper presents these concepts in the context of a platform development, namely FLAME2008, which is able to support its mobile users with personalized situation-aware services in push and pull mode.
